"It seems as though attacks against our agents are becoming more progressive and we have nothing to protect ourselves against the public," said Tammy Meadows, the Vice President of CWA Local 1182, which represents traffic agents.

In October, a pedestrian knocked out a 50-year-old Staten Island traffic agent with a single punch.

In August, an Uber driver was arrested for socking a Midtown traffic agent who issued a ticket for double parking.

"We are wearing a uniform with an NYPD patch on it. We are writing tickets that brings in revenue to the city and yet, we aren't protected all we have are radios," said Meadows.

Williams's attorney Chris Perks entered a not guilty plea on his behalf in court on Thursday.
